teners, of which the following description,

in connection with. the, accompanying draw ings, is a specification,like charactersbn the drawings representing like parts.

This invention pertains to improvements in separable fasteners and methods of secarrying fabric curing parts of the same to their carrying fabric. It is amongthe' 0b ects of the 1nvention to provide a simple and effective securing of'tlie socket of stud and socket fastener'sto a :carrying fabric, preferably without perforation of the fabric.

Referring to the drawings and to the preferred form of my invention selected for illustrative purposes, I have shown a fastener including a stud 8 of the general type shown in the (go-pending application of Fred S. Carr, Serial No. 351,780, filed January 16th, 1920, adapted to be secured to its carry- Specification of Letters Patent.

. from the stud,. the stuzisrtin'gw press th F. CARR, a cit -A fabric within the stud-securing" 10 and lnterlock these parts with the fabric between them. v v I '1 have also shown a socket 12, which preferably carries a spring 13, which may be secured therein by suitabl'e indented bosses 14, the socket preferably having a stud-receivmg aperturelf), which maybe notched at opposite ends to provide an interlock against separation by lateral strain, and, having exbe formed by a continuation of the flange 17 of the socket, the expansible continii'ation of the'socket rim preferably being slotted to facilitate expansion, as hereinaftenmore fully described.

Cooperating withthe socket, I may vide socket-securing means providinga means, herein shown as the lip 18, adapt -ate cooperate with the eiipansible ordistortable part 16 of the socket to the/socketcarrying fabric 19 therebetweeii. To, pre; vent relative displacement of the 16 and 18 in the general direction of thplane of the fabric 19, 1 preferably include oiithe socket-securing means apart 20 adapted to overlie the expanded projectionsf16 of the socket, and to provid e' for expansion-of the parts 16, I may provide anvil means 21oi1' the socket-securing parts. The parts 18, 20 and 21 may conveniently be formed as an integral 'rin'g, 'wl ich may be calleda. cap, especially where-the cent'er portion 22 thereof is filled inby the sheet ,of metal whic formsthe parts 18, '20 and 21.

To attach the socket to its carrying fabric,

the parts may be assembled in the position shown in Fig. 5, the socket 12 being located on one side of the socket-carrying fabric 19 and the socket-securing means being-located on the other side of the fabric. If, now, the socket is pressed against the socketsecuring part, the fabric 19 therebetween, the expansible projections from the socket will be deflected outwardly by the anvil portion 21 of the socket-securing means until. an interlock with the parts 18 of the socket,- securing element is effected. This expansion or distortion of the interlockingparts will be effected while the fabric lies between the part to be expanded or distorted and the anvil part, which effects the distortion. Where the cooperating parts are formed of relatively light sheet brass or other similar material, it will be found advantageous to provide dies adapted to be pressed one toward the other to effect the securing together of the parts, the dies preferably fitting the parts relatively closely to back-support the same and prevent undesired crushing of the parts which might in some instances arise if the setting force were unevenly applied.

It will be understood that I use the word fabric in its broader sense to include not only woven materials, but any flexible carrying medium.

lVhile I have shown and described a preferred form of one embodiment of my invention and apreferred method of practising the same, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A socket for separable fasteners comprising, in combination, a spring-containing element having an expansible part or parts and cooperating securing means for securing. the spring-containing part to a carrying fabric, said securing means located 'on the opposite side of the fabric from said spring-containing element and providing spreading means effective through the fabric for expanding said expensible part or parts, said securing means also providing means cooperating with said expansible part or parts for gripping the fabric.

2. A metallic-secured socket for separable fasteners presenting, when assembled with the socketcarrying fabric, a casing having an eXpansible part or parts, and a casing-securing part located on the opposite side of the fabric from said casing and providing spreading means effective through the fabric for expanding said expansible part or parts, said securing means also providing means cooperating with said expansible part or parts for gripping the fabric.

3. A metallic-secured socket for separable fasteners presenting, when assembled with the socket-carrying fabric, a dish-shaped casing having a stud-receiving aperture through the face thereof and a flaring rim, and a casing-securing part located on the opposite side of the fabric from said casing, said securing part presenting a peri heral bead, the outer wall of which underlies said flaring rim and the inner wall of which overlies said flaring rim, the fabric interposed and pressed between said flaring rim and the interior walls of said bead.

' 4. A socket for separable fasteners com prising but three parts,a socket casing, a spring therein and a socket securing cap, said socket casing and cap located on opposite sides of the socket-carrying fabric and securing the socket to the fabric by gripping the fabric between interlocking parts of the socket casing and cap.

5. A socket for separable fasteners comprising but three parts,a socket casing, a spring therein and a socket-securing cap, said socket casing and cap located on opposite sides of the socket-carrying fabric and securing the socket to the fabric by gripping the fabric between interlocking parts of the socket casing and cap while maintaining the fabric imperforate.

6. A metallic-secured socket for separable fasteners presenting, when assembled with the socket-carrying fabric, a dish-shaped casing having a stud-receiving aperture through the face thereof and a flaring rim, and a casing-securing part located on the opposite side of the fabric from said casing, said securing part presenting a peripheral bead, the outer wall of which underlies said flaring rim. and the inner wall of which overlies said flaring rim, the fabric interposed and pressed between said flaring rim and the interior walls of said bead and underlying a protecting central portion of said securing part.

In testimony whereof, name to this specification.
